. Application filed August 1,

a citizen or" the United States, residing at South Bend in the county ofSt. Joseph and State oi Indiana, have invented a certain new and usefulImprovement in Lighting Sockets and Holders, of which the following is aspecification.

M invention relates to lighting sockets and olders, especially thoseintended for in dustriul use in. factories, warehouses similar places.My device constitutes a conibined socket and reflector holder, and thegeneral object of the invention is to provide a device of this characterwhich shall have practically universal application and wh ch shall bestructurally simple and easy to in- I stall and work with. It will beunderstood by those familiar with the art that in incandescent lighting,especially in hidustrial buildings, the supply conductors lead to anoutlet box, and that sometimes it is desirable to locate the lamp bulbclose to or substantially at the outlet box, while at other times, it isdesirable to bring the bulb lower down into the room. For this purpose adown ipe or stem is usually employed, the bulb eing mounted at the lowerend of it. One of the specific objects of my invention is to provide asocket which lends itself with pan ticular facility to being attachedeither to the outlet box itself or to the lower end of the down pipe orstem. In my present form of device the conductive shell into which thelamp base screws is housed within a block or porcelain'which may beattached either to the outlet box or to a hood flange carried atthelower'end of the stem, the attaching means, being independent of theparts which perform any electrical function or which serve to fasten thereflector holder to the insulating block. Another object of theinventionis to provide a construction. in which the supply conductorslead through the body of, the insulating block to the bottom thereof sothat they may be connected or disconnected by simply manipulating ascrew driver from underneath the block. This makes it possible toestablish the electric connection after the insulating block has signhaving its own individual means of attachment' to the block and havingquick Specification of Letters Patent.

acting and efiicient means of attachment to and detachment from thereflector holder.

I accomplish my objects by the mechanism illustrated in the accompanyingdrawings, in which;

Figure l is an axial section of. the assembled device showing itfastened to the lower end of a stem and having a lamp bulb and reflectorin position. The plane of section is indicated by the line ll Fig. 3.

Similar numerals refer to similar parts throughout the several. views.

In the form selected to illustrate the invention, the block 1, whichforms the principal element of the structure, is of porcelain or otherinsulating material. It is chainbered at the bottom to receive andcircumferentially inclose a metallic shell 2, which is threaded to takethe base 3 of the lamp 4:, which is of standard pattern. The electricconnections of said shell are best shown in Fig. 5 where it will be seenthat the shell is connected to one of the supply conductors 5 by meansof a screw 6 screwing into a strap 7 electrically connected to bindingpost 8. The head of this binding post comes at the bottom of the blockand the supply conduc tor is led down to it through the verticalaperture 9, as best shown in Fig. 2. The other supply conductor is ledin a similar Way down through the aperture 10 in the block toconstruction lies in the fact that the final connections of theinstallation may be made at the bottom of the block after said block hasbeen fastened in final position.

The reflector holder of my device consists of a ring 18 having inwardlyprojecting lugs 19 which receive screws 20 by which the holder isfastened to the block IL The inner ends of the screws or studs 20 enternuts 2i held in chambers 22 formed in the block, as best shown in Figs.2 and 7. It willbe noted that by this construction, the reflector holderand the block become a unitary structure held together independently ofthe condition of the rest of the device.

The reflector holder is of special construction, having two lugs 24extending radially inward and adapted to engage the flange 25 of thereflector 26. By preference, these lugs are arranged about 120 apart,and 0pposite to them is a single set screw 27. This construction greatlysimplifies the act of attaching or detaching the reflector, for all thatis necessary in attaching it is to place the flange of the reflectorupon the two lugs as suggested in Fig. 8, then swing the opposite edgeof the flange up to the set screw and-then screw in said screw.-Similarly, by backing up the screw, the reflector'niay be removed. Notonly is the manipulation simplified, but the certainty and security ofaction is increased because the lugs, being a permanent part of thereflector-"holder, are in no danger of becoming loosened or beingimproperly positioned, as set) screws are apt to be.

The block 1 and shade holder 18 and shell 2 will usually be assembled atthe factory and hence constitute a unit ready for the reception of thelamp and the reflector and ready for attachment to the fixed electricalconnections attached to thebuilding. This unitary structure of theblock, shell and shade holder may be attached either to the hood-flange30, shown in section in Figs. 1, 2 and 6, or to the outlet box 35, shownin Fig. 7. The hood-flange is so named on account of its shape, andscrews onto the lower end of the stem 31 which leads the supplyconductors .to the fixture.

Said flange is' tapped to take the upper threaded end of.

aceat ductors 5 are connected, as before, to the lower end of thebinding posts 8 and 12. Nhen designed to be attached directly to theoutlet box, the plate 36 will beperinanently attached to the? block 1 bymeans of the screws 52 and in such case the plate would become a part ofthe unitary struc ture. of which the other principal parts are theblock, shell and the reflector holder.

It will be seen from the foregoing that the structure as a whole isgreatly simplified over previous devicesi'or the same purpose, and issimpler not only in construction, but is also easier tense and toinstall.

' Having thus described. my invention,

what I claim new and desire to secure by Letters Patent, is

l. A lighting socket having a block oi insulating material,lamp-engaging terminals housed within said block, binding posts con.

nected to said terminals and having means at the bottom of the blockforattachment to the supply conductors, said block being vertit-allyapertured to permit the supply conductors to pass down through thebloclrto the lower end of the binding posts, a plate fastened to the topof said block and pro jecting beyond the edge of the block, and means onthe projecting portion of said plate for attaching the same to asupporting objec 2. A combined lighting socket and reflector holderconsisting. of a bloclr of insulating material having terminals for thelamp housed therein, binding posts having heads at the bottom of theblock, said block he vertically apertnred to permit the conductors topass througl' lower end of the binding posts, a holding ring havingindependtat tening means for securing it to the bios; and meansindependent of the binding posts and indep i etorhclding ring to theblock, for supid block. 1
